| Popis: |
A prominent feature of the thermal structure of the Southwest Pacific Ocean between latitudes 40° S and 50° S is an isothermal layer of subantarctic mode water. This layer occupies the water column between depths of 400 and 600 m and has a temperature of 7–8°C. In winter, this feature can give rise to a surface sound channel down to 600 m and in summer can result in a subsurface subantarctic duct with axis at 100–250 m above a SOFAR channel with axis at typically 1200 m. The acoustic characteristics of this profile are examined and typical results are given for various source and receiver configurations. [Work supported by DSE and NUSC.] |
